start_devwait up to 45 seconds while watching for early process exitsrun-web-projectskill for diagnosing existing repositories and public sandbox previewsWhy
Preview startup previously returned a generic public-host error and discarded the development server output. That made dependency failures, missing environment variables, incorrect working directories, and server configuration problems difficult for the agent to distinguish and repair.
The public deployment boundaries also needed to be explicit before the project is shared more broadly: sandbox isolation does not make preview URLs private, and the reference app does not currently provide authentication or user isolation.
Impact
The agent now gets the actual startup failure and a small set of relevant diagnostics, while successful previews preserve the same flow. The README communicates the project's intended scope and security trade-offs prominently without adding authentication or product complexity.
